Constructing a Tubular Bell Array: Solving the Wave Equation

AI Thread Summary
To construct a tubular bell array, the wave equation for tubes needs to be established, similar to that for strings, but with specific considerations for the tube's geometry. The velocity of propagation in the tubes depends on the material properties, specifically the density and elasticity of the aluminum or copper used. Once the wave equation is formulated, it can be used to determine the frequencies required for standing waves in the tubes. Understanding how these factors interact is crucial for achieving the desired sound quality. The discussion emphasizes the importance of accurately defining the wave equation to successfully build the tubular bell array.

I have the next theoretical-practical problem. I have to build a tubular bell array (like that at symphonic orchrestas) with tubes (not rods) of aluminium or copper. The principal problem I have is I don't know how to state the wave equation for a tube (I have done it for a string). How I do it?

When I have the wave equation stated I must get the frecuencies to get a standing wave. Obviously this is what I want.

Could you help me?

If the bells are open at both ends, the wave equation is the same as for strings.
 
Ok but of what quantities the velocity of propagation depends on that's my problem.
 
The velocity of propagation is the velocity of sound.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
